>             Project: Groovy
>          Issue Type: Bug
>          Components: Static Type Checker
>    Affects Versions: 2.3.3, 2.4.0-beta-1, 2.4.0-rc-1
>            Reporter: Mauro Molinari

> Consider the following:
> {code}
> @TypeChecked
> class A {
>   @Bindable
>   String foo
>   
>   static void main(String[] args) {
> 	  A a = new A()
> 	  a.foo = 'old'
> 	  a.addPropertyChangeListener('foo') { event ->
> 		  println 'foo changed: ' + event.oldValue + ' -> ' + event.newValue
> 	  }
> 	  a.foo = 'new'
>   }
> }
> {code}
> The Groovy compiler fails:
> bq. [Static type checking] - No such property: oldValue for class: java.lang.Object
> This is unexpected, because if I leave the {{event}} naming of the closure input parameter and use {{it.oldValue}}/{{it.newValue}} the static type checking succeeds (as it should).
